APPARATUS FOR PRODUCING IMITATION TYPE-WRITTEN LETTERS.

Specification of Letter s Patent.

Patented Dec. 30, 1913.

Application filed. July 22, 1912. Serial No. 710,822.

To all whom it may concern:

Be it known that I, JAMES A. LooKwoon,

a citizen of the United States, residing at Denver, in the county ofDenver and State of Colorado, have invented certain new and usefulImprovements in Apparatus for Producing Imitation Type-lVritten Letters,of which the following is a specification.

My invention relates to a novel apparatus for producing imitationtypewritten let ters and its principal object resides in the provisionof a mechanism of simple construction which may be readily attached toan ordinary job printing press and which operates to impart toimpressions made from the type on the press, the ribbon effect which isdesirable in the production of imitation typewritten letters orcirculars.

Another object of my invention is to provide in association with theapparatus, means whereby the letter-head and the body of a letter areprinted simultaneously respectively without and wit-l1 the ribbon effectand, if desired, in different colors. I attain this object by themechanism illustrated in the accompanying drawings in the various viewsof which like parts are similarly designated, and in which,

Figure 1, represents a side elevation of an ordinary job printing pressto which my attachment has been applied, part of the crank wheel havingbeen broken away, Fig. 2, a fragmentary section along the line 22, Fig.1, looking in the direction of the arrow A, and drawn to an enlargedscale, Fig. 3, a similar section taken along the same line but lookingin the direction of the arrow .0, Fig. 4, a section taken along the lineFig. 3, and Fig. 5, a section taken along the line 5-5, Fig. 3.

In the drawings, 2 designates the sta tionary frame or body portion of ajob printing press of ordinary construction, 3 the oscillatory framewhich carries the chase 4 and the ink distributing disk 5, 6 theoscillatory member which at its end supports the inking rollers 7, 8 thecrank wheel which by means of a pitman 4C0 imparts a reciproeatingmovement to the frame 3, and 9 thetympan plate or platen which in theoperation is actuated by a cam 10 to press a sheet of paper fedthereonto from the feed table 12, against the type arranged in the form13 which is held in the chase on the oscillating frame.

My attachment consists of a standard 1 1 which is adapted to besupported and fastened upon the floor in adjacency to the press andwhich at its upper extremity has a laterally extending arm 15 the end ofwhich is turned downwardly to provide a support for a non-rotary shaft16 whose opposite end is fixed in an opening in the upright body portionof the standard.

Loosely mounted on the shaft 16 is a winding spool 17 the circularend-flanges 18 of which are peripherally toothed. An arm 19 pivotallymounted between two collars 20 on the shaft, carries a feed pawl 21 inengagement with the teeth of one of the flanges l8 and it is connectedwith a downwardly extending rod 22 on one of the collars by means of acoiled spring 23.

A second pawl 24 mounted on an arm 25 which is fixed on the shaft 16,engages the teeth of the opposite flange 18 for the purpose ofpreventing retrograde movement of the spool 1?. Attached to the outerend of the pivoted arm 19 is a cord 26 which being rove through tworings 27, respectively secured on the arm 15 and on the upright portionof the standard, is connected at its opposite end to a collar 28 whichis adjustably secured around the pitman 450 of the press.

An inked ribbon 29 of the character used on typewriting machines but oflarger proportions, is wound upon a spool 30 rotatably supported betweentwo plates 31 which are vadjustably secured at opposite sides of thestationary frame 2 of the press, and the opposite end of the ribbonwhich extends between the platen 9 and the chase 4 on the oscillatoryframe 3, is secured to the windns po IVhen in the operation of the pressthe type-holding element and the platen are moved together to produce animpression on a sheet of paper held upon the latter, the ribbon 29interposed between the said sheet and the body of type secured on thesaid element, will cause the impression of the type to be produced onthe paper in exact imitation of the work of a typewriting machine andwithout the aid of the inking mecha nism of the press. After eachimpression, the oscillating frame 3 moving away from the platen causesby means of the cord 26, an upward movement of the arm 19 against theaction of the spring 23 with the result that a determinate port-ion ofthe ribbon is fed onto the winding spool and a fresh part of the same isbrought in engagement with the type when the next impression is beingmade.

When it is desired to print on a sheet of paper a letter-head at thesame time that the body of a letter is being printed thereon, a ribbonis used whose width corresponds with the length of the body of theletter, as is shown in Fig. 2 of the drawings, in which the position ofthe ribbon with relation to the type in the form 13, has been shown bybroken lines 32, the type in the form from which the body of the letteris printed, having been designated by the numeral 33 and that whichproduces the letter-head by the numeral 3%. The composition around thecores of the inking rollers T has been eliminated with the exception oftwo portions 35 and 36 at opposite ends thereof, one of which is of awidth equal to the height of the letter-head for the purpose of inkingthe same during each movement of the oscillatory frame of the press,while the other serves to keep the rollers from binding by engagementwith an edge of the chase beyond the opposite end of the form.

Inasmuch as the type of the letter-head is not engaged by the ribbonwhile the impression is being made and the type of the body of theletter is not engaged by the inking rollers, it will be seen that ineach impression of the type in the form the letter-head will appear asusual, while the letter itself will have the appearance as if it hadbeen written on a typewriting machine and by supplying the ink rollerswith an ink of a color diiferent from that with which the ribbon isprepared, the letter-head and the body of the letter may be printedsimultaneously in different colors.-

After the entire length of the ribbon has been unrolled from the spool30 and wound onto the winding spool 17, it may be rewound on the firstmentioned spool by applying a crank to one of its trunnions by which itis supported on the plates 31.

Having thus described my invention what I claim and desire to secure byLetters- Patentis:

1. The combination with the platen and the moving type-holding elementof a printing press, of a standard separate from the latter, a windingspool rotatably mounted on said standard and including a toothed wheel,a spring-impelled arm pivotally mounted on the standard, a pawl on saidarm in engagement with the teeth of said wheel, and a cord connectingsaid arm with a part of said element.

2. An attachment for printing presses comprising a movable independentsupport, a winding spool and mechanism for rotating the same, mountedthereon in cooperative relation to each other, means for the directcooperative connection of said mechanism with a reciprocating member ofa printing press, a second spool, means to rotatably attach the same tothe frame of a printing press, and an inking ribbon wound on saidspools.

3. An attachment for printing presses comprising a movable independentsupport, a winding spool and mechanism for rotating the same, mountedthereon in cooperative relation to each other, a cord for the operationof said mechanism, a clamp on said cord for its direct connection withthe pitman which in the operation of the press converts the rotarymotion of the driving shaft thereof into an oscillatory movement of thetype-carrying frame of the same, a second spool, means to rotatablyattach the same to the frame of a printing press, and an inking ribbonwound on said spools.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
